IMPROVEMENT IN WAGON BRAKES. I

SPECIFIO.A TION.

TO ALL WHOM IT MAY CONCERN: v

Be it known that I, JOHN J. LOOK, of I Farmington, in the county of Franklin, and State of Maine, have invented a new and improved Carriage Brake; and I do hereby declare that the following'is a full, clear, and

exact description thereof, reference being had to the accompanying drawings, formi'ng part of this specification.

The nature of my invention relates to a brake which may be applied to'wagons and carriages, and is constructed and applied in such a manner that it acts automatically; when the wagon begins to press upon the team the brakes are at once brought to bearupon the wheels, which relieves the team from the pressure in descending a hill with a load. It also consists in constructing it in such a manner as to have one of the brakes applied tothc wheel by the lateral motion of the pole, so that in going around a curve down a hill, one of the brakes is brought to bear against the wheel on the inside of the curve. To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

The figure represents a top plan View of my improved brake.

Letters of like name and kind refer to like parts in the figure.

A represents the axle, upon which run two wheels B B, of ordinary or common construction. 0 is the pole, made of wood, and extends back' through between the braces D D, and passes througha mortise in the axle. E is the brake-bar, secured to the pole in a transverse direction, and extends across the hounds or braces D D, to each wheel. Upon the ends of the said brake-bar are fitted shoes F F, that are brought to bear upon the wheels B B, when the load or wagon presses upon theteam. ,The pole and brake are so arranged that, by a lateral motion of the pole, one of the brakes is brought in contact with the wheel, the advantages of which will be observed in going down a hill and around a curve; the brake upon the inside of the curveis brought to I bear against the wheel. FF F F are braces, running from the brake-bar to the pole, and from the axle to the hounds or braces D D. Now, it will be seen that, as the wagon presses upon the team, the pole slidesback in the axle and braces DD, which brings the brake-shoes hard upon the wheels, producing great friction thereon, thereby relieving the team from the pressure. It will also be observed that,-when it is desired to back the wagon, the pin H is introduced into the pole C, located at the forward ends of the hounds, at a. This pin has a bearing against the hounds so that the pole cannot slide back, so that no action of the brakes is applied to the wheels. 0 is a tapering enlargement of the hole C, made at the'point where the pole passes through the slot in the hounds D, and when the tongue is horizontal, or the carriage moving upon level ground, the pole G will be drawn forward, so that the elongated tapering enlargement 0 will accurately fit in the corresponding .slot in the hounds D, and the joint will be tight, and no rattling of the parts occur; but when the carriage is moving down a hill the pole C will be thrown back, and the smaller portion of the tapering enlargement will occupy thenslot in the hounds, thus allowing a lateral play of the pole, which, in conjunction with the braces F 'F, will, in turning a curve and descending a hill, throw hutono of the shoes, that upon the inside of the curve, into operation on its corresponding wheel.

Havin g thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

The pole G, provided with the tapering enlargement c, as described, in combination with the slotted hounds D, brake-bar E, lateral braces F F, and axle A, when the parts are so arranged that, by a lateral movement of the pole, one of the shoes only is brought to bear on its corresponding wheel, substantially in the manner and for the purpose set forth.
